Curbing apparatus

ABSTRACT

A curbing apparatus consisting of a manually operable wheeled vehicle for forming curb mix asphalt into a uniform curb. The vehicle carries a curb forming shoe with a hopper thereabove and a manually controlled shutter and plunger. The asphalt mix is loaded into the hopper. Operation of the shutter permits the asphalt mix to fall by gravity into the shoe. Operation of the plunger compacts asphalt mix in the shoe to form the mix into a section of desired curbing.

The vehicle carries a curbforming shoe with a PATENTEDJUHZZIQYE 35 5911 INVIL N I UR. JOHN VLAs/cCURBING APPARATUS SUMMARY OF THE INVENTION The curbing apparatus shoe ishorizontally elongated with an opening at the top and at both endsthereof. The shoe is open at bottom and is positioned close to theground or road. The hopper is disposed above the shoe and has a bottomopening in registration with the top opening of the shoe. A horizontalshutter is slidable back and forth between the openings. A verticalplunger supports one end of the shutter and extends to cover the innercross-sectional contour of the shoe. A manually controlled linkagepermits the shutter to be moved out of registration with the openingswhereby the mix falls through the hopper into the shoe, the plungerhaving been positioned remotely therewith. Thereafter, operation of thelinkage moves the shutter between the openings to block further loadingof the mix. At the same time, the plunger is moved toward the rearwardend of the shoe to compact the asphalt mix to form the desired curbingas controlled by the shape and size of the shoe. Wheeled means securedto the curbing apparatus and supporting the hopper permit the ap paratusto be moved from place to place.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1through 7, a curb forming shoe 10 extends elongatedly and horizontally,with sides 12 extending downward and outward, a top plate 14 which canbe curved or flat with a top opening 18 therein and opposite open endsand bottom. A hopper 16 is open at the top and has a bottom opening inregistration with the opening 18 in the top plate 14.

A horizontal shutter 20 is slidable back and forth in the area betweenthe hopper l6 and shoe 10 to be moved in and out of registrationrelative to the opening 18. One end of shutter 20 is carried by thevertical plunger 22. A horizontal bar 24 is secured at one end to theplunger 22 at 23 and at the other end is pivotally secured to the lowerend of the vertical portion 26 of a T-shaped member 25. The horizontalportion 28 of the T- shaped member is pivotally secured at 27 betweenthe horizontally elongated parallel supports 30 secured to the hopper 16at 29 and extends away from one end thereof. An inclined handle socket32 secured to portion 26 intermediate its ends receives handle 34. Ashandle 34 is raised, the shutter opens and asphalt mix present in thehopper falls into the shoe 10. As the handle is pushed down, the shuttercloses and the plunger is pushed into the mix to compact same to form acurb section 48.

The supports 30 each have a vertical sleeve 38 into which rotatablevertical shafts 40 extend to rotate a frame 42 supporting a wheel 44freely rotatable about a horizontal axle. Handle guides 46 are securedto the forward end of each support 30.

Should the curb section 48 need horizontal reinforcing rope or metalrods or the like, elongated sections of same can be manually introducedthrough the openings 50 in the plunger 22 prior to compacting.

The device described above can be used in the following manner.

A chalk line should be drawn to either left or right side of proposedcurb and used for a guide line. The pavement surface should be clean anddry before laying the curbing. Also a light tack coat of liquid asphaltin thin streamers should be used to aid in bonding new curbing onto thealready existing pavement.

The curbing apparatus should be sprayed with fuel oil inside of hopperl6, shoe l0 and on the plunger 22 before and after use. If stickymaterial is used, heat may be applied to the shoe, hopper and plunger.This will insure smooth operation of the curbing apparatus and finalsmooth surface finish on the new curbing.

The curbing apparatus is set at the starting point with the slantedrearward end 13 of the forming shoe at the point of beginning of theproposed curbing. With the hopper loaded to be approximately one-halffull, the plunger handle 34 is raised and material will drop into theshoe. When the plunger handle 34 is pressed down, it will compact toform the desired curbing. A shovel can be initially placed over the end13 of the shoe 10 to act as a stop to compact the initial beginning ofthe curbing. Upon compacting with the handle 34 and, when the rear end13 of the curbing apparatus starts to slightly lift, the apparatus willbe caused to move forward with every stroke of the plunger handle. Thepressure exerted on the handle 34 for compacting also moves theapparatus forward. The keeping of the hopper 16 full of asphalt materialwill aid in compaction. Compaction pressure can be increased if pressureis applied back on either handle guide 46 while the plunger handle 34 ispressed down. Also the making of short rearward strokes with the handle34 but not to the full extent of the stroke will aid in compaction ofthe asphalt material. Compaction can be also increased by loweringwheels 44 by vertical shafts 40 until proper curb height isaccomplished.

When approaching a turn or a radius in the curbing to be laid, thewheels 44 should be adjusted to desired are or curvature, and thecurbing will be formed according to the desired curvature.

It is always best to spray the parts of the curbing apparatus with fueloil when the desired curbing is finished or when stopping for any periodof time to avoid difficulties as to hardened asphalt material in againusing the curbing apparatus.

The curbing material may contain portland cement and more sand thanother mixes depending upon what is desired.
